Blog Article
These tables include only the most common host crystals; a lot of Other people exist, which happen to be considerably less frequently used.
In this article you may submit concerns and remarks. So far as they get accepted through the writer, they'll surface over this paragraph along with the author’s solution. The author will determine acceptance determined by specific requirements. Primarily, the issue have to be of sufficiently broad fascination.

激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
This is not hard to complete: just discover the lock icon before the URL in the deal with bar and drag that on the bookmark toolbar with the mouse. In case you discover the bookmark entry far too long, you can correct-click it to edit the text, e.g. making use of "RP Enc" rather than "RP Photonics Encyclopedia".
晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
Laser modeling and simulation may be used to reliably establish the optimum crystal Proportions, doping density And perhaps values of extra parameters.
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
For quasi-a few-level laser obtain media as well as a few-amount attain media, 1 usually should Restrict the size to a price and that is much too short for efficient pump absorption, as reabsorption effects would or else spoil the efficiency. For aspect pumping, further factors arrive into Perform; In addition to efficient pump absorption, it's important to get an appropriate spatial form in the obtain profile.

For different good reasons, composite crystals are getting to be popular. These Possess a spatially various chemical composition and might be designed with Distinctive shapes.
There exists a variety of crystalline media, which can Laser Crystal be grouped according to important atomic constituents and crystalline buildings. Some essential groups of crystals are:
